Project Overview
The replacement of bridge N-07-022 in New Braintree, Massachusetts, showcases how strategic planning and modern materials can significantly accelerate critical infrastructure improvements. Located on Hardwick Road, the bridge was nearing the end of its service life and required replacement to maintain safety and reliability for the local community.
Due to the critical role the bridge played in local connectivity and emergency access, the project was advanced on an accelerated timeline, making it an ideal candidate for Accelerated Bridge Construction (ABC) methods to reduce disruption to the surrounding area. The site-specific design called for the replacement of the bridge using seven (7) 4' x 33' precast, prestressed concrete deck beams. Following the completion of cast-in-place abutments, the project team worked efficiently to prepare for a highly coordinated beam setting operation.
Despite being relatively compact, the bridge replacement required tight scheduling and precision to meet the aggressive deadlines while maintaining high quality and safety standards. With a clear goal to reduce closure time and cost, precast concrete played a pivotal role in achieving those outcomes.
Precast Solution
Precast, prestressed concrete provided the foundation for this project's success - literally and figuratively. United Concrete Products, Inc., supplied all seven prestressed concrete deck beams used for the bridge replacement. Each 4-foot-wide beam featured in a rake finish on the top surface to ensure strong adhesion with the 3-inch asphalt overlay that would complete the deck system.
What truly set this project apart was the speed and precision of the precast concrete deck beam installation. All beams were set in a single day, demonstrating the power of advanced coordination and the reliability of precast concrete products. This rapid installation drastically shortened the construction timeline, contributing to an overall project delivery that was not only faster but also more cost-effective than conventional methods.
United Concrete's attention to detail ensured that each element met tight tolerances, enabling a smooth installation. The efficiency of precast concrete also supported the broader goals of Accelerated Bridge Construction - reducing on-site labor, minimizing traffic disruptions, and enhancing worker safety.
With the successful use of precast, prestressed concrete, this bridge replacement highlights the growing role of prefabrication in meeting today's infrastructure challenges. Precast, prestressed concrete elements allowed the project team to streamline scheduling, improve jobsite safety, and maintain strict quality control from production through installation. As demands increase for faster, more durable, and cost-effective construction, precast concrete continues to stand out as a smart solution for public infrastructure projects throughout the Northeast.
